<p>To limit global warming to well below&#160;2<sup>o</sup>C, integrated&#160;assessment&#160;models have projected&#160;that&#160;gigaton-per-year-scale carbon capture and storage is needed by c. 2050.&#160;These scenarios&#160;are unconstrained by limiting growth rates or historical data due to the limited existing deployment of the technology. A new approach using&#160;logistic&#160;growth models identifies a coupling between&#160;storage resource base (pore space underground) and minimum growth rates necessary to meet global climate change mitigation targets (Zahasky & Krevor, 2020).&#160;However, viable growth trajectories consistent with carbon storage targets remain unexplored at&#160;the&#160;regional&#160;level. Here, we show the application of&#160;logistic&#160;modelling constrained&#160;by climate change targets and assessed storage resources for&#160;the European Union (EU), the United Kingdom (UK), and&#160;Norway. This allows us to identify plausible growth trajectories of CCS development and the associated discovered storage resource base requirement in these regions.&#160;We find that the EU&#160;storage resource base is sufficient to&#160;meet storage&#160;targets of 80 MtCO<sub>2</sub>/year and 92 MtCO<sub>2</sub>/year&#160;suggested in the European Commission climate change mitigation strategy to 2050, &#8216;A Clean Planet for All&#8217;. However, the more ambitious goals of 298 MtCO<sub>2</sub>/year and 330 MtCO<sub>2</sub>/year are likely to require additional storage resources based predominantly in the North Sea. Results for the UK indicate that all anticipated storage targets to achieve net-zero economy&#160;are achievable,&#160;requiring no more than 42 Gt of the storage resource base for the most ambitious target. Furthermore, the UK and the Norwegian North Sea&#160;may be able to&#160;serve as a regional&#160;CO<sub>2</sub> storage&#160;hub. There are sufficient storage resources to support combined storage targets from the EU and the&#160;UK. The tools&#160;used here demonstrate a practical approach for regional stakeholders to monitor carbon storage progress towards future stated carbon abatements goals, as well as to evaluate future storage resource needs.</p><p>Zahasky, C., & Krevor, S.
